Improvements in Hurl Sizers and Shakers,

of which thefollowing is a description, reference being had to the accompanying drawlngs, which are a part of thisspeclfication.

new and useful improvements inhurl sizers and shakers employed in the manufacture of brooms.

One object of the present invention is to provide a machine of the class described ,WlllCll W111 have means for engaging and clamping therebetween the ends of the longer straws of a bundle of straws belng sized andhaving means for reciprocating the same to disengagetheshorter straws from the bundle.

Another object of the present invention ,is to provide two series of finger members or tines movable to engage in a bundle of straws to be sized in interlocked position and then whereby the same may be reciprocated to disfcome-withinthe scope of the claims."

engage the shorter straws therefrom.

[A further object of the present invention is to provide a machine of the class described employing finger members or tines connected together by lazy tongs to retain the finger members or tines of each series in the proper spaced relation with reference to each other.

A still further object of thepresent inven 'tion is to providea machine of theclass de' scribed including a main frameqhaving a table reclprocally mounted there n for receiving a straw container and having lazy tong means for moving. the same to various ad usted posltions 1n the mam frame.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more'particularly defined by the api pended claims, it' being understood that such changes .in,',the precise, embodiment (0f the hereindisclosed inyentionf may be, made as In the accompanying drawing I haveillustrated one complete, example ofthe physical embodiment of my invention constructedaccordlng-to the best mode I havetso far devised ,for the practical application for the chine'embodying the various features of 'my invention, parts being broken away and in section to more clearly, ,illustratethe various I details of construction. The present inventlon relates to certaln Fig-2 is a view taken through my machine at. right, angles with, respect to the view illustrated in Fig. 1, parts being broken awayand in section to moreclearly illustrate details ofconstruction. Y i

.Fig. 3 is a top plan viewof the two sets or series offinger members or tines illustrating .the same as'in disengaged position, ,the hanger members for supporting the same being removed.

Fig. 4 is anenlarged sectional view taken transversely. through the, lower ends of two of the finger member supportinghangers, and i Fig. 5 is a detail fragmentalviewofthe n I means, for releasably locking the finger movable to clamp the straws therebetween frame independent of the supplemental frame 7 is a tableor platform for supporting a container orreceptacle 10, to be later described. Lazy tongs 11 have the upper ends oftheuppermost links thereof pivotally connectedtothe tablet), as at l2,1and.have

one'of the lowermostlinks extended, as at 13,

beyond the otherlowermost link thereof, and

pivoterhtoflthesupplemental frame 7, as at 14,311.11 operatingulever 1 5,for vertically adjusting the position of the table Qbeing connected with the extended portion :13 of. the lowermost link by a'rod or. lever. 16and being pivotally connectedtoa fguadrant or rack'nie'rdberl? secured to the supplemental frame.

' Asbest shown ,in.,Fig. 1, the quadrant or raokrnember 17 suitableteeth formed on ,its periphery for retaining; vthe lever 15 in adj nsted, position, and i an fupward ,niovement ewee .1111 1ei'aeeelweg 1'1 and thus raise, or lower the table 9, and a movement of the lever in a reversed direction will lower the table 9. The straws, as indicated at 18, to be sized are positioned in the container 10, and as they are relatively loose the lower ends of the straws will engage V i the bottom of the container and thus position the upper ends of thelonger straws above the upperends ofthe shorter straws. After the straws have been so positioned the upper ends of the longer straws are clamped between finger members or tines 19 and the ("table 9, withflthe container 10-, is dropped and the fingermembers or'tines reciprocated by means of the supplemental frame 7 to disengage orshake' the shorter straws, not clamped by the finger members or tines. 19, from the bundle to' fall back into the con- 'tainer 10.

Fixed to the upper end of the supplemental frame 7 is a horizontalrack or frame 20 having guide grooves 21 on the inner face of its sldes for slidably' mounting therein a pa1r of guide frames or members 22, froniwhich the finger members orj' tines 19 are suspended, The members 22 are movable toward and away from each other in the'frame 21 by means ot a wheel or pulley 23 rotat'ablysecured to the member 21 medially of its ends and having trained there around suitable chains, or cables 24 and 25 trained about guide pulleys 26disposed at the outer ends of the frame 20. As best shown in Fi 1,the chain or Cable 24: is connected to be nested when moved to engage adjacent finger members, and said finger members are arranged in two series, one seriessupportel each series in even spaced relation,

the, outer upper end of one of the members 22, as at 27,.and thechain or cable 25 is connected to the lower outer end of; the other member 22, as at 28, so that upon the rotation of the wheel 23 in one direction the members 22 will be moved away from each other toward the outer ends of the frame 20, and upon rotation in a reversed direction the" members 22 will be moved toward each I 1 other and toward the cen terot the frame 20.

The finger members or tines 19 are angular in transverse cross section and arranged from each member 22. Each finger member [or tine l9lha's secured thereto the lower ends- 29 of an X'-shaped hangerl30 having the upper endsjof the upper'armsengaged about the transverse rod 31 which' has. itsends slidably mounted in guide grooves .32

formed in thesides ofthemembers 22, to thus; transversely movably support the finger members or tines 19 from the members 22.

The lower arms of the bracket members 30 of each series are connected together by guide rods v 33 to insure the even or smooth movement ofthe same and prevent the rods 31 from becoming twisted in the frame 22.

To always maintain, the finger' members oi the each other; -The hanger members 30 each have secured thereto medially of its ends a a spring member 38 which-abuts against the adjacent hanger 30 to thus normally urge the hanger members 30 with the finger 'members 19 to spaced position and means are provided for ,releasably looking or retaming the hanger members against move ment under action of the springs 38, as will be later described. y 7

, Then the straws 18 have been positioned as hereinafter described with the upper ends of the longer straws above the upper ends of move the members 22 toward the center of the main frame to'interlock or telescope the finger members 19 to engage therebetweeu the upper ends of the longer straws. When the finger members or tines 19 are telescoped engaging therebetween the upper ends of the longer straws, a'treadle'meinber 39 is the shorter straws, the wheel 23 is rotated to depressed which engages the upper ends .40

of a pair of bell crank levers 11" pivotally carried by the main frame with the side bars 36 off the series o1 finger members, thus urge ing the finger members of one series'to engage against'the adjacent finger members of the other series and thus firmly clamp the straws disposed therebetween. The finger means are thus retamed 1n clamping position by means of a latch bar 4-2,'1)ivotally carried by each side bar 36 and having a toothed outer e1id 4t3 adapted to releasably engage a keeper 4L4 fixed to the other side bar *ot' ea ch series whereby pressure from the treadle 39 ma be relieved and the timer i 8 'members still retained in clamping position.

lVhen the finger members are thus held H1 clamping engagement and the ends 40 of "the bell crank levers 4&1 disengaged from the side bars 36, the supplemental frame 7 is manually reciprocated to shake loose or disengage from the .bundle of straws 18 the shorter straws not engaged by the finger members 19., which shorter. straws fall back I into the container 10 and thusreadilyseparate from the longer straws. {The bell crank levers 41 are connected with the treadle 39 by means of toggle-links 4C5 having their outer ends pivoted to the lower ends of the bell crank levers 4:1 and-their inner ends connected to a cross heador block 46 which is connected to the treadle39 by means of a link 47. The: cross head 46 is normally urged upwardly by means of a spring 48 so that the upper ends 40 of the cross head will be normally urged to an inoperative position.
